[Gameplay] Urgot R 2 executes targets when it shouldn't

Simple: had an enemy Urgot land his R and activate it, while i (as Lulu) used R at the same time. Result: my Sivir was killed even if she had more than 25%. Eighter Lulu's R has to be refounded or Urgot should fail to kill the target, one of the 2 abilities shouldn't be able to proc.
